Webb26 maj 2024 · The genome of tobacco mosaic virus (TMV) consists of a single-stranded RNA molecule of about 6,400 nucleotides in length with positive polarity, which encodes at least four polypeptides: 126- and 183-kDa proteins required for transcription and replication (hereafter referred to as the 126K and 183K proteins, respectively), a 30-kDa (30K) … WebbThis was followed by evidence for double stranded RNA by Weismann and August in 1968. Reverse transcription is the process of making a double stranded DNA (deoxyribonucleic acid) molecule from a single stranded RNA (ribonucleic acid) template. It is called reverse transcription as it acts in the opposite or reverse direction to transcription.
